Class IntListIteratorToListIteratorAdapter

java.lang.Object
  bak.pcj.adapter.IntListIteratorToListIteratorAdapter

All Implemented Interfaces:

Iterator, ListIterator

public class IntListIteratorToListIteratorAdapter

extends Object

implements ListIterator

This class represents adaptions of primitive list iterators over int values to Java Collections Framework list iterators.

Since:

1.0

Field Summary

protected IntListIterator

iterator The underlying primitive iterator.

Constructor Summary

IntListIteratorToListIteratorAdapter(IntListIterator iterator)
Creates a new adaption of a primitive list iterator over int values to a Java Collections Framework list iterator.

Method Summary

void	add(Object o) Adds a specified element to the list at this iterator's current position.
boolean	hasNext() Indicates whether more values can be returned by this iterator.
boolean	hasPrevious() Indicates whether more values can be returned by this iterator by calling previous().
Object	next() Returns the next value of this iterator.
int	nextIndex() Returns the index of the element that would be returned by a call to next().
Object	previous() Returns the previous value of this iterator.
int	previousIndex() Returns the index of the element that would be returned by a call to previous().
void	remove() Removes the last value returned from the underlying collection.
void	set(Object o) Sets the last element returned to a specified value.

Constructor Detail

IntListIteratorToListIteratorAdapter

public IntListIteratorToListIteratorAdapter(IntListIterator iterator)

Creates a new adaption of a primitive list iterator over int values to a Java Collections Framework list iterator.

Parameters:

iterator - the primitive iterator to adapt.

Throws:

NullPointerException - if iterator is null.

Method Detail

add

public void add(Object o)

Adds a specified element to the list at this iterator's current position.

Specified by:

add in interface ListIterator

Parameters:

o - the element to add.

Throws:

UnsupportedOperationException - if addition is not supported by this iterator.

ClassCastException - if o is not of class Integer.

NullPointerException - if o is null.

hasNext

public boolean hasNext()

Indicates whether more values can be returned by this iterator.

Specified by:

hasNext in interface ListIterator

Returns:

true if more values can be returned by this iterator; returns false otherwise.

See Also:

next()

hasPrevious

public boolean hasPrevious()

Indicates whether more values can be returned by this iterator by calling previous().

Specified by:

hasPrevious in interface ListIterator

Returns:

true if more values can be returned by this iterator in backwards direction; returns false otherwise.

See Also:

previous()

next

public Object next()

Returns the next value of this iterator.

Specified by:

next in interface ListIterator

Returns:

the next value of this iterator.

Throws:

NoSuchElementException - if no more elements are available from this iterator.

See Also:

hasNext()

nextIndex

public int nextIndex()

Returns the index of the element that would be returned by a call to next().

Specified by:

nextIndex in interface ListIterator

Returns:

the index of the element that would be returned by a call to next().

See Also:

next()

previous

public Object previous()

Returns the previous value of this iterator.

Specified by:

previous in interface ListIterator

Returns:

the previous value of this iterator.

Throws:

NoSuchElementException - if no more elements are available from this iterator in backwards direction.

See Also:

hasPrevious()

previousIndex

public int previousIndex()

Returns the index of the element that would be returned by a call to previous().

Specified by:

previousIndex in interface ListIterator

Returns:

the index of the element that would be returned by a call to previous(); if no more elements are available in backwards direction, -1 is returned.

See Also:

previous()

remove

public void remove()

Removes the last value returned from the underlying collection.

Specified by:

remove in interface ListIterator

Throws:

UnsupportedOperationException - if removal is not supported by this iterator.

IllegalStateException - if no element has been returned by this iterator yet.

set

public void set(Object o)

Sets the last element returned to a specified value.

Specified by:

set in interface ListIterator

Parameters:

o - the new value of the element.

Throws:

UnsupportedOperationException - if replacement is not supported by this iterator.

IllegalStateException - if no element has been returned by this iterator yet.

ClassCastException - if o is not of class Integer.

NullPointerException - if o is null.
